Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 58138, here are decompositions:

29 + 58109 = 58138
71 + 58067 = 58138
89 + 58049 = 58138
107 + 58031 = 58138
191 + 57947 = 58138
239 + 57899 = 58138
257 + 57881 = 58138
347 + 57791 = 58138

Showing the first eight; more decompositions exist.
